MINERS LAMP.

EPECIFICATION forming part of Letters Patent No. 301,495, dated July 8,1884.

Application filed October 6, 1883. (No model.) I

To all 2072 0111 it may concern:

Be it known that I, J OHN HAMILTON, of Bellevue, in the county ofAllegheny, State of Pennsylvania, have invented a new and usefulImprovementin Miners Lamps; and I do here by declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon.

My invention relates to an improvement in miners lamps; and it consistsin providinga means for securing the lid intbe mouth ofthe lamp andpreventing the spreading of the side seam.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, which form part of my specification,Figure 1 is a vertical section of my improvement in miners lamps. Fig. 2is a transverse section of the ring I eniploy for holding the upper edgeof the mouth of the body in form and preventing the spreading of theside seam, and also for grasping the flange of the lid.

In the accompanying drawings, A represents the body of the lamp, B thelid, and C the metallic ring, having two flanges, e f. The upper edge ofthe mouth of the lamp is slightly flared outward, and is placedbetweensaid flanges. The outer flange, e, is secured to the upper edge of themouth of the lamp by the soldering process, thereby preventing thespreading of the side seam, g, of the body of the lamp, which side seamis often separated by rough usage, which separation will by thisarrangement be obviated. The flange f acts as a circular spring andclasps the flange D of the lid 13, thereby holding the lidin place andpreventing the escape of oil at the mouth of the lamp, the advantage ofwhich will be ap parent to the manufacturer and user of miners lamps.

Having thus described my improvement, what I claim is- In a miners lamp,the ring 0, having flanges e f, in combination with the body A and lidB, substantially as specified.

J OHN HAMILTON."
